Drilling
Oil and gas companies drilled 75 “high-impact” wells in 2024, representing 5.2 billion BOE.
This paper presents a comprehensive literature review of perforate, wash, and cement techniques that compares new methods with traditional ones and uses field cases and computational fluid dynamics to find the most cost- and time-effective practices without sacrificing safety.
The authors of this paper describe a method of stimulating a multizone hydrocarbon-producing well wherein a tool is deployed downhole by wireline to generate acid vapor at a target depth, allowing each interval to be treated uniquely.

At certain conditions, the good performance of synthetic-based mud (SBM) will degrade, particularly because of the effect of chemical instability under high temperature. Silicon dioxide (SiO2) nanopowder (nanosilica) holds the potential for performance improvement. -
Experience has revealed that frictional pressure loss in the wellbore hinders the full use of the entire length of the horizontal well. This paper presents a new approach to maximize the use of the full length of long horizontal drainholes.

This study compares the performance of openhole-packer completion systems with that of cemented-liner completion systems in the northern Montney gas resource play.
-
In horizontal and extended-reach wells in which long completions are run into highly deviated or lateral zones, large compression loads arise because of running friction.
-
The engineering and operational planning to ensure that no uncontrolled hydrocarbon releases occur during the execution of subsea big-bore gas wells are described.
-
Understanding drilling dynamics, the downhole shock and vibration that occur while drilling, is a crucial step to improving drilling efficiency and reducing nonproductive time (NPT).

With limited resources and lots of dedication, West Virginia University students wowed judges of the ATCE Drillbotics drilling automation challenge with the automated drilling device they built.
-
In organic shales, hydraulic fracturing is important for optimizing the production of horizontal wells. For a standalone lateral, the propped surface should be maximized to increase production. In the case of a pad, well spacing is an additional factor.

This paper offers an alternative explanation for the early boundary-dominated flow related to dissolution of salt-sealed natural fractures in the shale.

A Drilling Advisory System (DAS) is a rig-based drilling-surveillance and -optimization platform that encourages regular drilloff tests, carefully monitors drilling performance, and provides recommendations for controllable drilling parameters to help improve the overall drilling process.
